| Abstract |
Developing robust and predictable process simulation tools for CO2 capture is an important step in improving carbon capture technology to reduce man-made carbon emissions. Examples of available process simulation tools for CO2 absorption into amine solutions are the equilibrium based models in Aspen Plus and Aspen HYSYS and the rate-based model in Aspen Plus. Equilibrium based absorption models are based on the assumption of equilibrium at each stage. The model can be extended by introducing a Murphree efficiency (the ratio of the change in mole fraction from a stage to the next divided by the change assuming equilibrium). Rate-based models are based on rate expressions for chemical reactions, mass transfer and heat transfer. |
